I currently have 2GB of RAM (1GB in each slot) on the laptop and was looking to upgrade. Unfortunately, my version of the MBP maxes out at 3GB of RAM. Does anyone know if it is better to put 2GB in one slot and 1GB in the other vs. 2GB in each slot. Will the laptop benefit from having matched pairs even though it only can recognize the 3GB. I have talked to multiple people at Apple Care and get different answers. With RAM so cheap, i want the best performance and am willing to spend the extra $50. Thanks!
